Russia is continuing to warn the West of further attacks against Russia. Whether it be in the form of missiles or sanctions, the former Soviet Union doesn’t seem like they wish to play “war games” any longer.

The United States this month added several Russian firms and officials to a sanctions blacklist in response to what it said were the Kremlin’s “malign activities.” Moscow says those sanctions are unlawful and has warned that it will retaliate in a “painful” manner.

“No one should be under any illusions,” said Valentina Matvienko, who is closely aligned with the Kremlin, was quoted as saying by the Interfax News Agency. Matvienko, the speaker of the Russian upper house of parliament, said on Wednesday that Moscow’s response to any United States sanctions will be targeted and painful, Russian news agencies reported.

“Russia’s response to the sanctions, our so-called counter-sanctions, will be precise, painful, and without question sensitive for exactly those countries that imposed them [the sanctions] on Russia,” she was quoted as saying, according to Reuters. “Sanctions are a double-edged sword and those who impose them should understand that sanctions against countries, especially those like Russia, will carry with them risks of serious consequences for those who impose them,” Matvienko added.

Lawmakers in the lower house of the Russian parliament have drawn up legislation that would give the government powers to ban or restrict imports of U.S. goods and services ranging from medicines to software and rocket engines. However, the Kremlin has not yet said if it backs such measures.

A senior U.S. administration official said on Monday Trump has delayed imposing additional sanctions on Russia and is unlikely to approve them unless Moscow carries out a new cyber attack or some other provocation that would warrant sanctions.
